Ultimate submarine sandwich(sub)

Submarine sandwich. Yes, that’s what your favourite “sub” is actually called. This is my take on the regular fast food sub. My sub is unlike any other as it is a lot healthier, filled with the goodness and benefits of loads of vegetables in the veggie coleslaw, delicious pan-fried paneer that has a crispy exterior and  a soft, creamy interior. To top it all off, there is a layer of salted caramelised onion and cheese to finish the sub. This sandwich is all about building layers upon layers and adding a touch of magic and flavour to every single one of them. A portion of this wholesome submarine sandwich will satisfy your heart and fill you up in a jiffy. Share this awesome snack/lunch/dinner sandwich with your friends and family and surprise them with your cooking skills.

Bonus point: This sandwich can be made ahead of time and can be stored in the fridge so that you can enjoy it even after 7-8 hours. Make sure you warm it in the microwave or reheat it before eating if you store it in the fridge.

This recipe is for one submarine sandwich.

  • Preparation time: 15 minutes
  • Cooking time: 15 minutes
  • Total ime : 30 minutes

Ingredients :

  • French baguette (or any long bread loaf)
  • butter
  • 50- 75 grams paneer
  • lettuce or salad leaves of your choice
  • for the coleslaw: mayonnaise/hung curd – 2-3 table spoons, shredded cabbage (green), shredded cabbage (purple), shredded carrot, tomato sliced lengthwise and shredded cucumber.
  • 1 whole onion cut lengthwise
  • honey/sugar to caramelise
  • seasoning ingredients: salt, pepper, red chilli powder, cumin seed powder, chat masala and lemon juice.
  • cheese to top – use slices if you can.
  • oil to fry


  1. Start by preparing the coleslaw. If you want to make it healthier, use hung curd. To make hung curd, take fresh curd and put in a sieve or a muslin cloth and leave for up to 2 hours to let all the excess water drip off. This will form a thick and creamy curd which is a healthier substitute for regular mayonnaise. I used mayonnaise because I prefer it more. Add 2-3 table spoons of mayonnaise/hung curd (or more depending on the number of subs) in a bowl, followed by the shredded/grated vegetables. Make sure you squeeze out any excess water from the vegetables otherwise they will make the sandwich soggy. Then add in some salt, pepper and lemon juice and thoroughly mix the mixture. This is now a coleslaw.
  2.  Next step is to caramelise the onion. Start by heating some butter in a pan and then add the onion. Turn the flame on medium-low heat and constantly keep stirring until the onion turns brown and leaves a sticky, sugar coating behind. This is actually the caramelisation of the onion, the sugar breaks down as it gets cooked and makes the onion sticky. Then add plenty of salt to the onion to make salty caramelised onion. Cook it for a minute or so and then remove in a bowl.
  3. Third step is to shallow fry the paneer. Start by slicing the paneer into squares. After the paneer has been sliced, season with salt, pepper, red chilli powder, cumin seed powder and some chat masala on both sides. Now heat up a pan and add some oil, then place the paneer slices in the hot oil and fry on both sides till golden brown in colour and crispy. Remove from the pan and drain the excess oil on an absorbent paper and then transfer to a bowl.
  4. Now, shred some lettuce/ salad leaves. Make sure there is enough of it to cover the entire  bottom slice of the loaf.
  5. Last step is to assemble the submarine sandwich. For that, start by slicing the bread loaf into half along the length. You have to make sure that both the slices have the same amount of thickness. Layer the shredded salad leaves on the lower half of the loaf and make sure it is fully covered. Next, add the pan-fried paneer pieces. Be generous and make sure that every part of the loaf is covered with the paneer. Then generously layer the coleslaw on top of the paneer and cover the entire loaf to form a thick layer of coleslaw. On top of the coleslaw layer, add the salted caramelised onions in the form of a thick line and lastly, add shredded/sliced cheese on top and season once again with some pepper. Put the top half of the loaf over to complete the submarine sandwich.
  6. You can bake this in the oven till the cheese is melted. I have done that but If you do not have an oven/microwave, you can omit this step as it is not very important.
  7. Slice in even portions and serve with tomato ketchup.
